Rectangular and Radial Layouts
Switch between a classic cladogram (rectangular) and a circular radial view — ideal for compact display of large, complex trees.

What is a Phylogenetic Tree Chart?
A phylogenetic tree chart maps the evolutionary relationships between species, genes, or organisms, branching from a common ancestor to show how lineages diverge over time. It is the standard visualization in biology, genetics, and bioinformatics for presenting cladogram or dendrogram data. Use it whenever you need to show how closely related two groups are, trace mutation spread, or illustrate the hierarchical structure of any branching system. Our free online phylogenetic tree chart maker lets you build and customize these diagrams in seconds using AI.
Key Features
Proportional Branch Lengths
Toggle proportional branches so distances accurately reflect evolutionary time or genetic divergence between nodes.
Per-Clade Color Coding
Assign distinct colors to each clade, making it easy to distinguish major lineages at a glance.
Node Collapse and Zoom
Collapse subtrees to focus on specific clades, and pan or zoom into dense sections of large phylogenies.
Branch Length Labels
Optionally display numeric branch length values on each edge to provide quantitative evolutionary distance data.
AI-Powered Tree Generation
Describe your taxa and relationships in plain language — the AI builds the tree structure and assigns branch lengths automatically.
Best For
Evolutionary biology and taxonomy research
Virus and pathogen variant tracking (e.g. flu or COVID strains)
Comparative genomics and gene family analysis
Linguistic family tree visualization
Cladogram presentations in academic papers or lectures
Microbiome and 16S rRNA diversity studies
When to Use
- When you need to show hierarchical branching from a common ancestor
- When comparing genetic or evolutionary distances between multiple groups
- When tracing how a pathogen or species diversified over time
- When presenting cladogram or dendrogram data to a scientific or general audience
- When a simple hierarchy chart cannot capture divergence and branch-length information
Common Mistakes
- Disabling proportional branches when evolutionary distance is the key message
- Adding too many leaf nodes without collapsing subtrees, making the tree unreadable
- Using vague node labels like 'Group 1' instead of actual taxon or sequence names
- Choosing rectangular layout for very large trees — radial layout handles 50+ nodes far better
- Omitting branch length values when the audience needs to assess relative distances
- Treating the root as a definitive real ancestor without noting whether the tree is rooted or unrooted
